Is it bad to have thoughts constantly?

I've been single for a while...and I've tried to wait to have cuz I wanna find a decent guy in order to have something meaningful...HOWEVER, it's been a looooong while and I'm really craving it! and I need to have more than just a vibrator...I want the real thing. So how do I make these thoughts stop?! or should I just give into temptation and just have a fling even though it's not meaningful? *sigh* What to do?!
